Lenticular Lens Display Panel Pixel Aperture Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional image display devices suffer from deteriorated display quality due to non-display areas caused by shading portions in the display panel, which restrict optimal viewing positions and lead to incomplete image recognition.
Innovation Solution
The design incorporates a display panel with pixel sections arrayed in a matrix, featuring optical units that sort light into different directions, and display areas where middle points between ends have varying distances from the optical axis, minimizing non-display areas and enhancing viewing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a parallax barrier or lenticular lens system is used to display three-dimensional images, then multi-viewpoint imaging capability is achieved, but non-display areas appear due to shading portions restricting light paths
Solution Approach 1:
The patent introduces a third dimension (depth/distance) to the display area configuration. By making the distance from the optical axis to the middle point of the display area vary depending on the position in the second direction (depth), the patent creates a three-dimensional display space that eliminates non-display areas while maintaining multi-viewpoint capability through controlled light paths in multiple spatial dimensions
2Adaptability or versatility
If shading portions are added to the display panel to enable viewpoint separation, then image sorting for multiple viewpoints is achieved, but display quality deteriorates due to non-display areas
Solution Approach 1:
The patent applies local quality by configuring different display areas for different spatial positions. The distance from the optical axis to the middle point of each display area varies according to the position in the second direction, creating locally optimized light paths that ensure complete image coverage while maintaining viewpoint separation through position-dependent optical properties
3Ease of manufacture
If the display area is configured with fixed geometric parameters, then manufacturing is simplified, but non-display areas occur when viewing positions deviate from optimal points
Solution Approach 1:
The patent introduces dynamic characteristics to the display area configuration by making the distance from the optical axis to the middle point variable depending on the position in the second direction. This dynamic geometric configuration allows the display system to adapt to different viewing positions automatically, eliminating the need for fixed optimal viewing points while maintaining manufacturing feasibility through systematic parameter variation

Function Achieved in This Case
This configuration suppresses the occurrence of non-display areas, thereby improving display quality by ensuring light reaches all intended areas, allowing for optimal viewing positions and reducing the impact of shading portions.

AI summary
In an image display device where a lenticular lens, a display panel, and a light source are provided in order from a viewer side, when cylindrical lenses of the lenticular lens are arrayed in a horizontal direction, in first-viewpoint pixels and second-viewpoint pixels of the display panel, openings whose sides which intersect with straight lines in the horizontal direction are not parallel to a vertical direction are formed. And, a shape of the openings of a pair of pixels mutually adjacent in the vertical direction is made line-symmetric with respect to edges of the pixels extending in the horizontal direction as an axis.
